How to Fix a Blown Head Gasket?

Head gaskets in a truck are usually vital in the smooth running of the engine and the entire truck despite their small size. However, at times, the head gaskets often get compromised due to several reasons. Suppose this problem is not fixed in time, and you continue driving around the car. In that case, you may end up escalating the damage due to possible high-temperature gradients in the engines and mixing of the coolant with combustion fumes and oil.


Therefore, fixing a blown head gasket may take two approaches.

First Approach

You may take the car to a mechanic and instruct them to replace the blown head gasket and any damaged parts with new components. This is, however, often quite expensive. Thus, many people opt for the second option involving the use of a sealer and can be done at the comfort of your home garage.

Second Approach

This is usually much cheaper and convenient; however, it requires strict adherence to certain steps and guidelines to achieve the best outcomes. These steps include;

1. Preparation: This involves first acquiring all the required and necessary tools. These include first and foremost, the best sealer in the market for the job. There are numerous brands; thus, you should strive to get the best. You may also check your toolbox to see if all your tools are available and ready for use. Finally, make sure that your engine is cold before you move to the next step.

2. Cleaning out and Filling up the Radiator: Make sure that your radiator has clean coolant. Thus, if the ones inside are dirty or contaminated, you should flush it out and put in new coolant. In this step, you may also check on the specific location of the leak by taking out spark plugs from every cylinder, if the car uses many cylinders until you find the ones with anti-freeze on them. Then, you should leave the affected cylinder open while also unplugging the fuel injector to the specific cylinder so that it doesn’t fire.

3. Addition of the Sealer: Before going further, you should first shake the gasket sealer container thoroughly to ensure that the solution is uniform and will thus flow smoothly. Then, you may now remove the radiator cap and place it somewhere safe, pour all the sealer into the radiator then seal it up.

4. Starting and Running the engine: After the above step, you will then start the engine and set the heat to maximum. The engine may, however, not start at the first try; therefore, you should be patient and give it time to pick up.

You will then need to leave the engine running for close to half an hour. This is to allow the coolant and sealer mixture to travel throughout the coolant system to reach the targeted spot, the head gasket.

5. Re-evaluating the new state of the head gasket: Turn off the engine and allow it to cool for at least an hour, and then you are good to go. However, you may always repeat the process three or four times just to make sure that the sealer properly holds the leak and leave the car to cool down at least overnight.

After the above step, your car is ready all you have to do is reassemble the disassembled parts and take the car out for a spin but remember to start slow for the blown gasket to adjust. You will also need to check for the symptoms of a blown head gasket such as white smoke on the exhaust, traces of coolant in the drained oil, engine misfires, and hot engine temperatures.


The Final Words (Conclusion)


Any individual can do the above steps, or you can always opt to seek professional assistance. Nevertheless, it is the cheapest of the methods for fixing a blown head gasket, and thus you should give it a try if your gasket is compromised. If these fail, then your leak may be extensive thus warranting for a more surgical approach of removing and replacing the gasket altogether by a professional mechanic.
